Mooney (foot), who was listed as a limited participant on all three of the Bears' Week 12 practice reports, doesn't have a designation for Thursday's contest at Detroit.
Meanwhile, No. 1 wide receiver Allen Robinson (hamstring) didn't practice and was listed as doubtful for a second week in a row, signaling that he'll likely miss another game. During last week's loss to the Ravens, Mooney notched a career-high 16 targets and turned them into five catches for 121 yards and one touchdown. Starting quarterback Justin Fields left in the second half of Sunday's game due to bruised ribs and won't play Thursday, meaning Mooney will be on the receiving end of passes from Andy Dalton, with whom he connected on a 60-yard score Week 11.
